<h2>Detailed Description</h2>
<p>The QStylePlugin class provides an abstract base for custom <a href="qstyle.html">QStyle</a> plugins.</p>
<p>QStylePlugin is a simple plugin interface that makes it easy to create custom styles that can be loaded dynamically into applications using the <a href="qstylefactory.html">QStyleFactory</a> class.</p>
<p>Writing a style plugin is achieved by subclassing this base class, reimplementing the pure virtual <a href="qstyleplugin.html#keys">keys</a>() and <a href="qstyleplugin.html#create">create</a>() functions, and exporting the class using the <a href="qtplugin.html#Q_EXPORT_PLUGIN2">Q_EXPORT_PLUGIN2</a>() macro. See <a href="plugins-howto.html">How to Create Qt Plugins</a> for details.</p>
<p>See also <a href="qstylefactory.html">QStyleFactory</a> and <a href="qstyle.html">QStyle</a>.</p>

<h2>Member Function Documentation</h2>
<h3 class="fn"><a name="QStylePlugin"></a>QStylePlugin::QStylePlugin ( <a href="qobject.html">QObject</a> * <i>parent</i> = 0 )</h3>
<p>Constructs a style plugin with the given <i>parent</i>.</p>
<p>Note that this constructor is invoked automatically by the <a href="qtplugin.html#Q_EXPORT_PLUGIN2">Q_EXPORT_PLUGIN2</a>() macro, so there is no need for calling it explicitly.</p>
<h3 class="fn"><a name="dtor.QStylePlugin"></a>QStylePlugin::~QStylePlugin ()</h3>
<p>Destroys the style plugin.</p>
<p>Note that Qt destroys a plugin automatically when it is no longer used, so there is no need for calling the destructor explicitly.</p>
<h3 class="fn"><a name="create"></a><a href="qstyle.html">QStyle</a> * QStylePlugin::create ( const <a href="qstring.html">QString</a> &amp; <i>key</i> )&nbsp;&nbsp;<tt> [pure virtual]</tt></h3>
<p>Creates and returns a <a href="qstyle.html">QStyle</a> object for the given style <i>key</i>.</p>
<p>The style key is usually the class name of the required style. Note that the keys are case insensitive. For example:</p>
<pre> QStringList MyStylePlugin::keys() const
 {
     return QStringList() &lt;&lt; &quot;Rocket&quot; &lt;&lt; &quot;StarBuster&quot;;
 }

 QStyle *MyStylePlugin::create(const QString &amp;key)
 {
     QString lcKey = key;
     if (lcKey == &quot;rocket&quot;) {
         return new RocketStyle;
     } else if (lcKey == &quot;starbuster&quot;) {
         return new StarBusterStyle;
     }
     return 0;
 }</pre>

<h3 class="fn"><a name="keys"></a><a href="qstringlist.html">QStringList</a> QStylePlugin::keys () const&nbsp;&nbsp;<tt> [pure virtual]</tt></h3>
<p>Returns the list of style keys this plugin supports.</p>
<p>These keys are usually the class names of the custom styles that are implemented in the plugin.</p>
